Re: .300 RUM reloading ?????\'s
Dont overlook the 190 SMK. I think you will find it will blow the doors off the 180 SMK at 1000 yards. More the desighn than the 10 more grains.
Long range shooting is a process that ends with a result. Once you start to focus on the result (how bad your last shot was, how big the group is going to be, what your buck will score, what your match score is, what place you are in...) then you loose the capacity to focus on the process.
